Each lung is divided into lobes by fissures. The right lung has three lobes separated by two fissures (horizontal and oblique), while the left lung has two lobes separated by one oblique fissure.
The mediastinum, a broad, middle tissue partition, separates the lungs from each other and divides the thoracic cavity into two parts. It contains vital structures such as the heart, esophagus, trachea, and major blood vessels.
The scalene fissure is located in the lateral aspect of the lung. It separates the lower lobe from the middle lobe in the right lung.
The superior border of the temporal lobe is marked by the lateral sulcus, also known as the Sylvian fissure. It separates the temporal lobe from the frontal and parietal lobes.
The central fissure is a deep groove on the surface of the brain that separates the frontal lobe from the parietal lobe. Its main function is to divide the brain into two hemispheres and help with the organization of different brain functions in each hemisphere, such as motor and sensory processing.
The central sulcus runs along a fissure in the brain and is located in the parietal lobe. It separates the frontal lobe from the parietal lobe and plays a role in dividing motor and sensory regions of the brain.
